Product Description

Petroleum Refinery can be used in black engine oil, crude oil,Pyrolysis oil and shale oil, to get gasoline and diesel oil through distilled catalyst. Pumping into the heater with raw material , through the gas,fuel oil or coal heating to working temperature, the maximum working temperature of Rice bran oil refinery equipment to make edible oil about 410 degree and the required gasoline and diesel oil can be obtained after catalytic distillation. When the reaction of Petroleum Refineryraw material in reactor is complete, stop heating, and remove residue from the tank of bottom, then Rice bran oil refinery equipment to make edible oil can be used again.

Refined edible oil is one kind of vegetable oil for human grade cooking, you can get the oil from oil seeds like soybean, peanut/groundnut, palm seeds, rapeseeds, mustard seeds, sesame seeds, sunflower, corn germ and other kinds of oil seeds.

Traditional method is press the seeds by hands, foot or some simple tools to press the seeds and extracting the vegetable oil. By this way, the oil yield will be very less, there still have about half of the oil stay with the cake, this will decrease the farmer's profit and waste natural resources.

Rice bran oil refinery equipment Main parts :

1.Neutralization tank:It is used for phosphoric acid degumming,alkai deacidification washing.

2.Bleaching tank:It is used for removing pigment,grease bleaching&dehydration.

3.Deodorization tank(by stainless steel):It is used for removing odor and peculiar smell.

4.Conduction oil furnace:It can provide the steam for deodorization.

5.Steam generator:It can provide the steam fo deodorization.

6.Vaccum pump:It can provide the vaccum for dehydration,bleaching and deodorization.The vacuity can reach above 755mmHg.

For some oils, such as sunflower oil or rice bran oil, a clear table product is obtained by a dewaxing step or crystallization of the wax esters at low temperature, followed by filtration or centrifugation.

The alkaline neutralisation process has major drawbacks, the yield is relatively low and oil losses occur due to emulsification and saponification of neutral oil. Also, a considerable amount of liquid emuent is generated. The soaps are generally split with sulphuric acid to recover free fatty acids along with sodium sulphate and some fat-containing acid water steam.

In physical refining, the fatty acids are removed by a steam distillation (stripping) process similar to deodorisation. The low volatility of fatty acids (depending upon chain length) requires higher temperatures in physical refining than those required for only deodorisation. In practice, a maximum temperature of 240-250°C is sufficient to reduce the free fatty acid content to levels of about 0.05-0.1 percent. A prerequisite for physical refining is that phosphatides be removed to a level below 5 mg phosphorus/kg oil. In the classic refining process, this level is easily achieved during the neutralisation stage, but special degumming processes may be required for physical refining of high-phosphatide seed oils. These procedures rely on improved hydration of phospholipids by intimate contact of the oil with an aqueous solution of citric acid, phosphoric acid andlor sodium hydroxide, followed by bleaching (Segers and van de Sande, 1988).

It is unlikely that the mild reaction conditions during degumming and neutralisation will induce any significant undesirable changes in the oil composition. On the contrary, several impurities including oxidised components, trace metals and colouring materials are partially removed by entrainment with the phospholipids and soapstock. These impurities are further reduced during bleaching. Neutralisation also contributes significantly to the removal of contaminants such as aflatoxin and organophosphorous pesticides (Thomas, 1982). Organochlorine pesticides and polycyclic aromatic hydrocarbons, if present, must be removed during the deodorisation/stripping stage and by active carbon treatment. Some loss of tocopherols and sterols during alkaline neutralisation usually occurs, however, under wellcontrolled conditions (minimising air contact) this need not exceed 5-10 percent (Gertz, 1988; Johansson and Hoffmann, 1979).
